Release 2.1.3

=============



* Improvements to CallChainOfFunctionPointerswithContext:

  - add a `detach` function to be able to remove callbacks.

  - detach function now return true if a function has been detached and

    false otherwise.

  - add a function call operator.

  - use safe-bool idiom. see : http://www.artima.com/cppsource/safebool.html



* Add SafeBool class which allow to easily declare a safe bool operator in

  c++03.



* Improvements to FunctionPointerWithContext:

  - fix call propagation

  - use safe bool idiom



* Add config file for generating Doxygen.



* Setup for onRadioNotification callback does not call initRadioNotification

  anymore.



* GapAdvertisementData now handles replacement and appending of data fields

  based on type. Some fields can be replaced with new values, and others

  require the payload to be appended.

rgrover1 710:b2e1a2660ec2 957 * Radio Notification is a feature that enables ACTIVE and INACTIVE
rgrover1 710:b2e1a2660ec2 958 * (nACTIVE) signals from the stack that notify the application when the
rgrover1 753:0f60274cd3ad 959 * radio is in use.
rgrover1 710:b2e1a2660ec2 960 *
rgrover1 993:4d62b7967c11 961 * The ACTIVE signal is sent before the radio event starts. The nACTIVE
rgrover1 993:4d62b7967c11 962 * signal is sent at the end of the radio event. These signals can be used
rgrover1 710:b2e1a2660ec2 963 * by the application programmer to synchronize application logic with radio
rgrover1 710:b2e1a2660ec2 964 * activity. For example, the ACTIVE signal can be used to shut off external
rgrover1 993:4d62b7967c11 965 * devices, to manage peak current drawn during periods when the radio is on,
rgrover1 710:b2e1a2660ec2 966 * or to trigger sensor data collection for transmission in the Radio Event.
